GE 1900/65A Equipment Monitor

GE’s 1900 Series self-contained monitors are designed to address essential and balance-of-plant (BOP) equipment assets that require continuous machinery protection but do not warrant the cost of larger, more sophisticated rack-based monitoring systems like the 3500 Series. 1900 monitors provide a simple and cost-effective way to apply machinery protection on selected machines or points and are designed to operate as stand-alone units, or in conjunction with our Trendmaster® Pro on-line condition monitoring system.

Features and Benefits
  • Designed as a stand-alone, multi-channel monitoring system targeting essential and balance-of-plant (BOP) equipment
  • Compact size
  • Multi-function ability
  • Trip multiply functionality to reduce unwanted machine trips
  • Easily-configurable and flexible dynamic channels for speed or position of vibration
  • Cost-effective product and installation (via 232 or 485 connectors)
  • Simple to apply on selected machines or points
  • Added support for RTD type temperature sensors

The 1900/65A General Purpose Equipment Monitor is designed to continuously monitor and protect equipment that is used in a variety of applications and industries. The monitor’s low cost makes it an ideal solution for general-purpose machines and processes that can benefit from continuous monitoring and protection.


The 1900/65A provides four transducer inputs and four temperature inputs.

Software can configure each transducer input to support 2-and 3-wireaccelerometers, velocity sensors or proximity sensors. Each temperature input supports Type E, J, K, and T thermocouples, and 2-or 3-wire RTDs.


The 1900/65A provides six relay outputs, four 4-20 mA recorder outputs,and a dedicated buffered output. The user can use the 1900 Configuration software to configure the relay contacts to open or close according to the OK, Alert and Danger statuses of any channel or combination of channels, and to provide data from any variable from any channel on any recorder output. The dedicated buffer output can provide the signal for each transducer input. A Modbus Gateway option allows the monitor to provide static variables, statuses, event list, time and date information directly to any Modbus client, including Distributed Control Systems (DCSs), Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs), or System 1 software. The monitor uses an internal counter and a Modbus client/master time reference to generate time and date information. Users can upgrade monitors without the Modbus Gateway by ordering the 1900/01 Communications Upgrade (see the Ordering Information section). The 1900/65A supports Modbus communications via Ethernet and a software-configurable RS232/485 serial port.


The user defines monitor operation and the Modbus Gateway register map by using software running on a laptop or PC to create a configuration file and download the file to the monitor through the built-in Ethernet connection. The 1900/65A permanently stores configuration information in non-volatile memory, and can upload this information to the PC for changes.
